Frameworks. I have some Nordic nrf52840 USB Dongles, along with Makerdairy nRF52840 and Fanstel. The profile can be created by: Using the USB CDC, the data sent by Blue Pill was not received by an old Terminal Serial written via Delphi 7; (serial monitor in PlatformIO) as my serial monitor programs and saw no output -- believing that something was seriously broken. I created a simple project in STM32CubeIDE and confirmed that I just need Disclaimer: sorry for the long reply I’m really excited with the principles behind platformIO. What if I could use the UPDI pin as a general GPIO pin and have You signed in with another tab or window. Tried with the exact same debugger setup and simple Arduino setup() and loop() functions on an Arduino Nano33 BLE board (Nordic nRF52480 processor) and the USB CDC enumerated successfully. Thus, first upload any sketch using CDC enabled option from Arduino IDE in order to, in the next board reset, have CDC working and make it understand USB signaling for software upload and board reset. The Serial2 out put is connected to a RS485 interface. As the board uses USB and does not have any serial USB chip, I cannot know what is being sent to the tx pin, but I can see from the oscilloscope that it is always sending the same data continuously, I believe the board is in a data loop. Configuration. Altough there are many forum Q&A dealing with various problems and aspects of flashing and debugging ESP32(-S3) I am using Visual Studio + Platform IO to config and compile MARLIN for my 3D printer.

It works fine in Arduino, but PIO complains it can’t Yes, I understand that: Your code is printing to Serial and Serial0. Am using an Adafruit s3 Feather. For the USB CDC host, the ESP-IDF example cdc_acm_host is a good starting point. Also, take a look at the actual esp32 arduino USB CDC doc. The current state of my platformio. Or we can use the USB capabilities of the STM32 to create a virtual COM port for us. I recently started using the WT32-SC01 Plus, and have been developing with it with few issues for the most part (I had trouble getting it to work when I first I think I’m pretty close to the correct config. TL;DR You can have exactly what you wanted with the internal usb peripheral. 5 kOhm (this is often an issue with blue pill boards). x or have downloaded the arduino-cli utility, then you can create a “profile” which is very similar to the platformio. 0 FYI, USB DFU is just one of protocols a USB hardware device can identify itself to the host as having, just like USB CDC is another one (for serial comms) as is USB HUD (for devices like mice, keyboards, joysticks and such) and USB Mass Storage (for USB flash disks and similar data storage devices). delay(1000); } And platformio. I have a display connected where I want to see the text output. I got this problem after a fresh installation of PlatformIO run as sudo. if I use board = esp32-s3-devkitc-1 I That’s part of the reason for the upload vs upload with programmer targets the upload target has the -D parameter set to prevent auto-erasure, as the bootloader takes care of the programming of the MCU, whereas the programmer target lets the auto-erase occur. If timer's frequency TIM_FREQ=1000000 Hz (1MHz), so one tick = 1 us. As thus, Serial should be using the native USB-CDC capabilities of the ESP32S3 chip. With Arduino IDE, and with the Arduino framework on PlatformIO, I can upload a sketch and monitor serial output without issue. I have an STM32 based on the STM32L4+ series, and I’m using PlatformIO to try to make use of USB OTG to connect a USB keyboard for text input. py, which is not capable of decoding the HID serial console opened by the teensy. They both are just listed in the device manager as keyboard+mouse+joystick. I can then download a test program and both UART and LED works, however if I try to use SPI1 I get many errors, change to stm and it complies file , but cannot download. It works correctly on my Linux PC, comes up as /dev/ttyACM0 just like a plugged in Arduino does. platformio. I’m using an Arduino Uno with a shield I made that I’ve been programming successfully with the Arduino IDE, but I’m trying to migrate all my IDE needs to PlatformIO, but programming ATTiny chips has There’s also the posibility of programming a barebones ATTiny85 with an external programmer but that then also defeats the purpose of using the Digistump. What would be a platformio. This function will block until the target device is connected or timeout My project uses ESP32-S3-WROOM-1 Soc with a USB C port connected to D+ and D-. If the port cannot be found when uploading the program or the USB has been used for other functions, the port does not appear. You just need the to get the setup (in the ide / your config) right. None of the examples will compile out of the box under PlatformIO. capture_hid_report. But if I press the reset button, serial communication is interrupted and the terminal does not reconnect automatically, We would like to show you a description here but the site won’t allow us.

All I could find indicate that once USB_CDC_ON_BOOT is enabled the Serial Monitor is using CDC instead o Hi, I have been looking for two days on forums at potential interaction between USB CDC and UART0 on an ESP32-S2. I’ve tried everything I can think of but the only thing that worked was to define a SoftwareSerial but that won’t allow me to easily debug other libraries I’m using. Setup Details: Board: BluePill (STM32F103C8) Bootloader: Installed (specify if it’s the Arduino Can you upload the exact project files which, when uploaded, make the COM port of the Nano ESP32 disappear? Bonjour, Explication rapide de mon problème. 1 but PlatformIO is still on 2. This will reset the contents of the flash I think all you have to do is to enable CONFIG_ESP_CONSOLE_USB_CDC in sdkconfig and disable all UART related log settings. My first guess is I will need updated USB descriptors to support the additional devices, can I use custom USB Descriptors with this core, or do I need to revert to pick-sdk? This project exposes 6 ports Hi All! For the latest platformio (at the moment), if you set board_build. I have installed lib-usb drivers using zadig and flashed for the first time shorting IO9 and GND The CH340G USB-to-UART chip is used by a number of inexpensive development boards (e. So all in all, you should rather use this platformio. println("Hello world"); SerialUSB. For the platformio. With S2-SOLO I cannot: 1 - print using log_x. Top. 4T Hi, I use both ESP32-C3 and ESP32-S2-SOLO chips. This blog post delves into the platformio. Let's see how to use hardware timer interrupt (RTOS not used) from the timer with real tests on the devboard and measurements using logic analyzer to confirm correctness of the code. You can use any shell or programming language. Hello, I have been trying to get the USB facility on the ESP32-S2 for some time. Single USB-C connector wired to pins 19 (USB_D-) and 20 (USB_D+). (For USB to work I need a CPU clock of 96MHz as this leads to a USB-clock of 48MHz. Unfortunately, it often causes problems on macOS. 0 and STM32F4, Difficulty with getting USB serial [USB CDC] working, among others, but none brought me to a solution. I the use maple as source. x including LeafLabs Maple and other generic STM32F103 boards and it compiles, program fine with a ST-Link V2 dongle. py the changes are all I’m trying to create a lot of CDC ports on the same device - but I seem to be limited to 4 even if I set CFG_TUD_CDC higher, say 6 when using the maxgerhardt PIO platform. Every upload via usb is a pain. Arduino. In the case of the M5Stamp S3, when looking at the schematics, it appears that there is no USB-to-UART adapter chip on the board, the ESP32S3 is connected directly to the USB-C plug. 2 documentation Hello, good day, I’m new to MCU programming. Optimized to speed time to market-and easily adapt to new ones-they are based on the industry’s most code-efficient architecture for C and Hi, I’m attempting to use the built-in jtag debugger with a ESP32-S3-DevKitC-1, unfortunately I’m running into a problem. I’ve added it to PlatformIO and simple sketches are compiling without any issue. The problem it that when I have it in the case the only USB port I can access is the one on the separate debug board and that uses a CH340 for USB to UART. The board is a “black pill”, containing an STM32f103C8T6. Debugging.
