With the current "typedef struct" for peripheral handles, callback code that deals with multiple instances of a peripheral, such as uarts, CANs, etc., often has to do a lookup a lookup on the handle passed to it by the peripheral callback. If the ha...
Receiving TCP stream that spans two packets fails after several seconds. Pings still work. The STM32F7 replies to the receive stream with duplicate ACK'sThe TCP stream does not recover.Ethernet Receive Logic Review using STM32Cube_FW_H7_V1.3.2/Proj...
On a STM32F042K6 (using the latest CubeMX software and FW_F0 V1.9.0), we have code that goes into "Stop" mode to achieve low power. A pin connected to PA0 (EXTI0) wakes us up.This all works great. Except that we can get the system into a state wher...
Hello everyonei using Timer 1 and set PWM on CH1 and CH2N CH1 is work fine but CH2N not working (i checked pin work fine on nromal GPIO)my code only have two line :HAL_TIM_PWM_Start(&htim1, TIM_CHANNEL_1);HAL_TIM_PWM_Start(&htim1, TIM_CHANNEL_2);any...
Hello,i have a strange problem when i try to work with a FatFS on SD cards with SDIO.MCU is a STM32F439ZI, SDIO 4 wire for SD cards, FatFS for SD cards (used CubeMX 5.1.0 to create the base code, working with Atollic TrueSTUDIO 9.0.1)I have working c...
Hi, how do i send data to the CS43L22 codec on the board? In the audio example, it sends 16bit uint values with the eval_audio_play, but on the HAL_SAI_transmit functions i can only send 8bit values. I cannot find a solution, i configured the DAC and...
HiI use the STM32L452 configured as a USB CDC device which is connected to a host PC.Once every 1-2 weeks the communication breaks down in the OUT direction as seen from the host.In other words the host receives data, but it's not able to send anythi...
Hi all,Where I can find a complete ST FreeRTOS documentation?Thanks
HelloI'm using an STM32F103T8 who talks over CAN interface with a Raspberry Pi (MCP2515 Controller). The MC also uses USART1 for communication with a sensor module.For testing purpose I've setup a simple program which sends continuously can frames of...
