Posted on March 30, 2016 at 18:25Hi, I am looking how to save a few bytes in RAM. I am using the standard peripheral lib, and included in stm32f10x_rcc.c, stm32f2xx_rcc.c and stm32l1xx_rcc.c, I found some static constant arrays (PLLMulTable, APBAHBP...
Posted on March 25, 2016 at 17:06Hallo, I'm developing on a board based on STM32F407 and FreeRTOS, FatFS, and LwIP. The code is generated by Cube 4.13. The problem is that during a test with a continuous ping (-f) the board doesn't receive messages ...
Posted on March 26, 2016 at 14:40 Hi ST community, I am working on CAN communication using STM32F042F6P6 (20 pin, PA11/12). During initialization (CAN_Init function), I am receiving INAK_TIMEOUT (stuck in a while loop for cca 25 seconds)...
Posted on March 26, 2016 at 22:57Hi!Is there any chance to supply external power supply to STM32F429I-DISC1? When I connect 5V to 5V pin nothing happens, except blinking LEDs from ST-LINK and display highlight. Maybe RESET is always active or someth...
Posted on March 18, 2016 at 15:43Hello,i want to use the analog watch-dog 1 interrupt with the STM32F334.I configure the peripheral with CubeMx.But the interrupt is never serviced. I must enable the EOC or EOS interrupt to get the Analog watch-dog c...
Posted on March 30, 2016 at 13:14 Does DMA has FIFO buffer of commands? My task is to read multiple bytes from different registers via I2C alternately. Could I just write like this: /*Somewhere in code....*/ HAL_I2C_Mem_Read_IT(&hi2c2,...
Posted on March 30, 2016 at 12:59hi, My RTC is driverd by external 32.768K clock source. It works well，if the MCU does not enter standby mode. Let the MCU enter standby mode and wake up every 60 seconds by alarm, RTC will slow about 6 seconds durin...

Posted on March 15, 2016 at 18:17Hi, I'm trying to get USB CDC to work. The sample project with USB CDC works and it outputs Hello\r\n, however, when I've added additional tasks and I2C usage, the application is stuck inside in an infinite loop insi...
Posted on March 30, 2016 at 01:29I've posted this on Atollics site too but thought I'd ask here also. Added some modification code to a example project and was successful ! Except now my code appears in the editor and NONE of the *mouse rollover a f...
