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...
Posted on June 13, 2016 at 20:38Hi all, I work on a USB project with my STM32F103. I want to use USB HID because it don't need any driver and it easy to integrate with the help of Cube32MX. i can sucessfully send data from STM32 to PC and grap it wi...
Posted on June 13, 2016 at 09:52RM datasheet specify that ADEN must be 1 before configuring CFGR, SQRx ... HAL_ADC_Init library configures these registers with ADEN= 0 Which procedure is the right one ? #adc-config
Posted on June 09, 2016 at 11:57Hello masters , Is there any kind of way or register that PWM counter is counting up or down in center aligned mode? I need to control the system depends on up counting. So i have to check timer counts up or down . ...
Posted on June 13, 2016 at 16:56 Hi everybody. I have an stm32f4 micro trying to communicate with device via UART. I want to receive with interrupts and possibly, based on some conditions, stop the reception process (i.e. if some time exp...
Posted on June 12, 2016 at 22:17HiI am going to develop a customize board based on STM32F072RB IC. I am searching for some application circuit, but couldn't find any. However I got some help from STM32F0 Discovery board schematic but it's confusing....
