Posted on August 24, 2015 at 12:59Hi all, I'm using UDP Echo client code example in STM32F217xx.I can send the custom buffer...ok but I can't receive udp packets from PC. I have a VS code that can generate UDP test packets as well... I use the udp_r...
Posted on June 10, 2016 at 19:20I have seen several people use the ''cat /dev/USB<some number>'' can get information from the board printed to a Linux terminal via USB cable. I have followed a few guides (http://www.carminenoviello.com/2015/03/02/ho...
Posted on June 14, 2016 at 17:09Tried to post a reply to my older posting asking about this but it says ''page not found'' hence the new post. I think I found the issue. Down in the bowels of WM8994 setup the driver is setting registers 0x29 and 0...
Posted on June 13, 2016 at 20:32Hi, I have evidence that the UART embedded bootloader of the STM32F070CBT6 does not work. Is this expected ? I have tried the boot sequence with other STM32 variants for years, and I cannot find any written explanatio...
Posted on June 12, 2016 at 05:29Hey folks, I am trying to implement an SMBUS protocol on an STM32F29 board using the HAL-I2C drivers. Main purpose is to be able to read a MLX90614 temp sensor and report the output to the screen. I am getting some od...
Posted on June 11, 2016 at 18:31Hello,I started using USB CDC device in my project which uses F303RE controller. I struggled to get it working until I realized that it is most likely using same DMA channel that I'm using for SPI3 access. I'm using D...
Posted on June 10, 2016 at 12:43I have a curious problem on my STM32L151. I have the USB running in double buffering mode, and I can get a transfer rate of ~10MBit/sec. But after I unplug the USB cable, and plug it back, the transfer rate drops to ~...
Posted on June 09, 2016 at 14:20 I am working with the Discovery Development Board and I would like to receive data over a software UART. In the code below I would expect to receive 8 timer interrupts if only 1 byte is transmitted, but 100 micro...
Posted on June 13, 2016 at 16:33 Hi, I have found a bug inside functionTIM_SetIC2Prescaler() fromSTM32L1xx_StdPeriph_Lib_V1.3.1,which is the latest version. The current code is: void TIM_SetIC2Prescaler(TIM_TypeDef* TIMx, uint16_t TIM_...
Posted on June 13, 2016 at 19:32RM0351 ('L4) rev.4, ch.6.2.8, in two (2) places - in text and table - mentions ''Product voltage range''. My guess is, that it is supposed to read ''Power voltage range'', and that that chapter should contain a link t...
