Posted on September 04, 2015 at 14:22 I have this code: while (1) { if(fUSB_rcv) { CDC_Transmit_FS((uint8_t *)''Mensaje Recibido\n\r'', 18); HAL_Delay(10); if (msg[0]=='L' && msg[1]=='E' && msg[2]=='O' && msg[3]=='1') { CDC_Transmit_F...
Posted on April 07, 2016 at 15:11Hi, I use 2 UART ports: UART1 for WiFi and UART4 for debug output. My goal is to send to UART4 data I received on UART1. When I use only 1 UART, it works (UART4), everything I typed on keyboard, returned back. I impl...
Posted on April 02, 2016 at 12:40Hi,I am facing some weird problem in UART.Whenever i am using UART in polling to receive the data followed by storing the data into some array. But what is happening is that the array is sometimes(mostly) starts to f...
Posted on February 21, 2015 at 19:40Hello I just need a confirmation. Is there really no support for firmware upgrade over USB (DFU) in the STM32L0 MCUs??? The STM32L0 is not listed in the http://www.st.com/st-web-ui/static/active/en/resource/techni...
Posted on April 01, 2016 at 06:19Hello, I'm trying to drive DS12B80(One-wire interface)using F030. Thus I initiated a PWM output channel 4 and a input capture channel 1 of TIM3. And the DMAs are started with: HAL_TIM_IC_Start_DMA(htim,TIM_CHANNEL_1,...

Posted on March 31, 2016 at 21:57Hi,We're trying to reduce power consumption when not suspended and using USB. During the time when we are not handing USB interrupts, we would like to run at a slower core clock speed. I'm wondering if this is poss...
Posted on March 21, 2016 at 19:59I've created nearly identical projects using CubeMX.First one is using STM32F107, 2 ADCs, ETH. When I compile it and run on my target (EasyMX Pro v7 for STM32 ARM), it gets to main loop without problems.The only diff...
Posted on March 24, 2016 at 13:11Having problems getting this to work. I discovered that optimisation may have been the cause of a couple of errors. So, if I turn off all optimisation in SW4STM32 (eclipse IDE + gcc toolchain), I can get the F7 disco...
Posted on March 29, 2016 at 21:14How to use HAL_I2C_Master_Transmit() from outside main.c This HAL_I2C works when I call it from within main.c. I created some external i2c_routines.c, but have a hard time defining how/where to get and use HAL_I2C_Ma...
