Posted on February 21, 2018 at 17:27Hey, I am facing a specific task and I could really need some help with that. So I have many stm32L073 µC which all run the same programm. The programm has a stored list of constants in them which are used while ...
Posted on November 21, 2017 at 03:40I use stm32cubemx version 4.23. When I use SDIO 4bit and FATFS middleware, I see USE DMA Template option. If I choose 'disable', my code will run correctly. But If I I choose 'enable', I can't read and write data ...
Posted on February 22, 2018 at 08:56 I have implemented a small program with STM32F103C6 to initialize ADS1115 and read data from it via I2C using STM32cubeMx & HAL. Can I integrate this program into an other project which uses SP...
Posted on February 21, 2018 at 10:02I generated my code from STM32CubeMx and wanted to generate a update event every 1µs. I work with the internal clock at 48MHz, which should be with Prescaler:0 and Autoreload:47 result to 1µs.I use a STM32F030 w...
