Posted on October 06, 2015 at 08:52I have an STM32F0 which is receiving and transmitting serial data. When I send the data another board responds. If I poll RXNE looking for the data and store it in an array like this everything works: //while ((USA...
Posted on October 05, 2015 at 09:46I need to receive a lot of SPI data on a STM32F4. To handle this, I use a DMA buffer in circular mode. Also, I need to use the CRC feature. How ever this seems not to be possible with the HAL according to this note...
Posted on October 06, 2015 at 13:46 I recently run into a problem while using the following: Crossworks v2.3.5.201401120385 with a STM32F407ZG Cortex-M4 It goes like this: I installed an external SRAM (AS6C4016A-45ZIN, 512KB) on the FSMC...
Posted on October 06, 2015 at 11:28Hello there,I am using HAL library with FreeRTOS middleware. The minimum delay I can use for the osDelay() function seems to be 1 ms. I would like to turn on task periodically every 10 or 100 ns. Is that even possi...
Posted on October 06, 2015 at 12:58 Hi. I'm trying to combine TJpgDec and DMA2D. However, the display shows white square. UINT output_func(JDEC *jd, void *bitmap, JRECT *rect){ static DMA2D_HandleTypeDef hdma2d_eval; WORD h =...
Posted on October 05, 2015 at 19:42Hello,my name is Carlo. I'm a student new to STM32 and MCUs in general.What I'm trying to do is to send a 16-bit ADC value through USART to PC, using stm32f0. I found some troubles doing this since USART takes one ...
