Hello! I'm working on project requaring CAN node. I decided to quckly check if the periphery is configured correcltly. For this purpose I connected two pull-ups resistors to Rx and Tx pins and tried to see some bits on the oscilloscope.I configured G...
Hello everyone, I have been learning to work with USB connection in STM32 and while my research I've noticed that some schematics have D+ line pulled up to +5V, when in stm32 dev board schematics and in AN4879 it's pulled up to 3.3V and that's what I...
Good morning,I am trying to develop a touch screen screen controled by a STM32F1 and connected to a PC throught USB port.My doubts are related with the USB comunicationI've found many examples for USB comunication as Virtual COM or as a Mouse/Joystic...
Hi there,I have an old joystick which i want to convert to a custom hid device, the stick has three shiftin registers (cd4201) which i am reading using spi1. I know these shift register are being read cause i am sending it to serialport3 (just for de...
We have designed a custom bootloader solution that works on multiple STM32 devices, however when we attempted to use it on STM32L496VE we realised HAL_FLASHEx_Erase did not clear the flash, even though it returned HAL_OK.On further investigation, it ...
STM32F4-DISCOVERY board: I need to read from the mic (MP45DT02) and I was trying to use the STM32CubeIDE to generate the initialization and I cannot get to enable the pdm2pcm middleware. I have tried to configure I2S2 (no errors) but still pcm2pcm is...
Dear ST community,I am running stm32f4-7 with FreeRTOS, and lwip, I am running TCP server by use of LWIP and some other application logic. I need to generate PPM signal (8 PWM pulses with different length) every 20ms. For this purpose I am using time...
I'm using STM32F446, I found one issue. In STM32F4xx_hal_uart.c, it stated that. ============================================================================== ##### How to use this driver ##### ===========================================...
I build the whole program by the IDE. Following is my code. I can read the CID of the card without select the fatfs middleware. The program report FR_DISK_ERR in f_open. The f_mount works fine.int main(void) { /* USER CODE BEGIN 1 */ /* ...
Hello,I have my custom board and it has 3 different memory area (pyhsically) and they are, Internal 64K flash which has 2x32KB sectors, Parallel NOR Flash 64 MBit which has 128KB sector size, 128MBit QSPI Flash which has 64KB sector size.If i use onl...
