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...
Posted on November 30, 2017 at 13:54Hi, I'm working with a STM32L053R8 and I want to use some ADC pins. I have a doubt about the input voltage range. Does the ADC have an independent power supply? Which is the input voltage range of the ADC?For exam...
Posted on November 29, 2017 at 13:56Hi, I'm trying to make a little project just to send an echo of what is received over USB. I have been able to do it, but there s something I couldn't do yet.My code in the USB callback function is as shown belo...
Posted on November 25, 2017 at 20:17Hello I am using this microcontroller for a project with ethernet. From what I've been reading everyone recommends that I use MII instead of RMII since RMII incurs in a lot of packet loss. And reading the errata I...
