Posted on December 04, 2017 at 04:21Hi, I am working on a project that needs to read audio signal from 4 PDM microphones. I checked that STM32F405 chipset has 2 muxed full-duplex I2S. Is that mean I can read 4 channel audio data with this mcu? Is th...
Posted on December 04, 2017 at 23:33I need to update DAC in PWM.I have STM32F103C8T6 and two free timers (TIM3, TIM4).But they only have one global interrupt. How do I get PWM?I'm only called HAL_TIM_PWM_PulseFinishedCallback() and I get the meander...
Posted on December 04, 2017 at 03:51 I use STM32 Cube to config USART2 to transmit data to computer. I don't enable USART2 Interrupt. I use DMA for USART2 Tx only (DMA1 Stream 6).uint8_t Data_to_send[5000]; __IO uint8_t Probe=0;int main(void) { HAL...

Posted on December 02, 2017 at 03:42 Hi, I just took two days to trace a bug that only appeared when I was doing concurrent reads & writes on my SD card from separate threads in FREERTOS. The bug is in sd_diskio.c and needs fixing intwo fun...
Posted on November 29, 2017 at 18:27 Hi all, I've started a new F401 project, but for the life of me I cannot find the setting in CubeMX to have it create usbd_conf.h using the static malloc replacement: /* Memory management macros */ #def...
Posted on August 09, 2017 at 15:21I am working with the HAL RTOS generated through cube and generally speaking, so far so good. I am used to using FreeRTOS but am a little stumped with this HAL RTOS, more specifically the timers. I have generated th...
Posted on December 01, 2017 at 04:40I am working with STM32F407 Discovery Board and micro SD Card. I use STM32CubeMX version 4.23 to config SDIO 4 bit.This is my code to read data from micro sd card: FATFS myfatfs; FIL myfile; uint8_t SD_Data_Read_A...
