Posted on July 17, 2016 at 17:13Hi, I just got a Nucleo STM32L031K6 board and start playing with STM32Cubemx. For my project I need to use the low power timer LPTIM to trigger another timer (e.g. TIM2) but I have no clue how to do this. Could someo...
Posted on June 16, 2012 at 15:32hi everyoneneed help regarding UART with DMA mode,i am using STM32F407 Discovery Board,i want to configure UART4 with DMA, and want it to generate interrupt when DMA completes filling the memory. so should i configure...
Posted on March 18, 2014 at 20:08 Hi, I use LWIP and FreeRTOS like WEB server. It's OK. But now, I want send data to otger page for example by GET. Like this: http://www.page.com/p.php?json=1234 Can you help me please? Here is my co...

Posted on July 23, 2016 at 02:50Does STM32F103RB use switched capacitor ADC circuit which produces some noise in the process and requiring source impedance to be 'not too high' or else accuracy will degrade? The signal is single channel and no MUX...
Posted on July 23, 2016 at 02:44What configuration parameters (clock freq, sampling clock count, etc.) can I tune in order to minimize ADC reading noise when sensing a relatively low speed signal? I am currently getting about 10 to 20 LSB differe...
Posted on July 22, 2016 at 14:15Does STM32F103RCT support flash read protection? I cannot find any introduction on datasheet. Is it only available on XL density 103?103RCT is high-density flash device. In CUBE nucleo package, I can not find code abo...
Posted on June 05, 2015 at 03:03Wrote some code for STM32F429I-Disco that writes data in flash but it denied to work in USB receive function. ''static int8_t CDC_Receive_HS(uint8_t*Buf,uint32_t*Len)'' But it did work in main. What can it be? uint32_...
Posted on July 23, 2016 at 01:31We are using an STM32 on a board, and have issues with its sleep current. Under normal 2 x AA voltages the system works well, but as part of our testing we take it higher. We have found the current draw on the STM in...
Posted on July 22, 2016 at 22:31Is it true that 2 to 3% accuracy is required? Nucleo F103 has no crystal. Nucleo F401 has 32kHz crystal
