hello.I am using STM32F407VGT6 chip and trying to send data to PC with USB CDC function.But in the below function, the TrySendUsbPacket() function is not executing due to queue full phenomenon.void EnqueueUsbPacket(const uint8_t* data) { uint16_t ne...
I can't get TIM1 to trigger DMA in my code (main.c)Am I missing something?
Hi all,I have a strange issue that I can't wrap my head around.I have an eMMC chip connected to a STM32U5G9The .IOC file is all standard: with the clock config as follows: However, when I start a debugging session I get stuck in the init function lik...
Hi there,I would like to control WS2812B LEDs with a PWM timer and DMA.There are various tutorials on this, but they have not helped me and I am now asking you. Because it requires slightly different configurations depending on the model (F3, F4, G4,...
I was trying to build a flight controller with this board. I was using rizacelik's repo for this project. At first, i was using the 3.0.1 firmware .hex file but then later wanted to switch to the newer 8.0.0 firmware so i flashed the newer .hex file ...
I have tried USB examples for Stm32F070, F401, F407 Black board and calling a single "CDC_Transmit_FS" function to print a string but none is working. The hcdc->TxState value is some garbage big value so it always stay busy and also not getting inter...
I used Cude IDE version 1.18.1. successfully then upgraded and wrote the second project (timer). I'm using Nucelo-64 STM32 F411RE with clock rate 84Mhz. My new project is to use the TIM4 with the settings: PSC: 8399, CP: 10000 to toggle the LED per ...
I've been previously programming the STM32F103C6T6 blue pill with an FTDI via UART and am now trying to flash a USB bootloader binary to program it directly via USB.I've closely followed the guide on https://www.electrosoftcloud.com/en/stm32f103-boot...
