Posted on July 19, 2016 at 09:06 I am using SPI to communicate with an external NVM memory and hope to have some data validate at the end by using CRC. But I do not understand how does the SPI CRC calculation contribute to verify the data that I...
Posted on July 20, 2016 at 03:05 HI: i can't find StdPeriph Drivers in RTE when i use KEIL for stm32l does it not support?
Posted on July 20, 2016 at 00:08I am using Keil uVision, and occasionally, at start of debug, the program counter would stuck at the Rest handler routine below. The execution would point to the instruction: ''BLX R0'' (line #2) and woul...

Posted on July 19, 2016 at 13:19Hi everyone, I have designed a board using stm32f407vgt6 and placed a 8MHz crystal oscillator with 22pF capacitors. The code I wrote works perfectly with stm32f4discovery. But when I try to use my board, it can't init...
Posted on July 19, 2016 at 13:58Dear All,I am facing a strange problem. I am using a slave SPI to transfer memory data by a DMA stream. The transfer uses 16-bit wide data. On the stm32f429 (m4) the code works very well and I can use the data. The sa...
Posted on July 18, 2016 at 11:48 Hi. I have added USB Host support for MSC. It is working ok with USBs under 4gb... but it is not detected properly with USB-sticks over 4gb. I'm using library version 2.2.0, microcontroller are F2/F...
Posted on July 19, 2016 at 10:47Hello, I'm working with an STM32L152C discovery trying to get the RTC to output a calibration signal. When configured to output a 512Hz signal it works as expected, however when set to output 1Hz, the processor crashe...
Posted on December 08, 2014 at 16:06 Hello I'm using a STM32F303CC lqfp 48 on a new product. I'm trying to use 3 Usart channels. I succesfully use channel 1 and 3 but channel 2 is acting weird. In configure the three channels all in the s...
