Posted on July 25, 2016 at 03:50I know that I2C's official speed is 100KHz (Standard Mode), 400KHz (Fast Mode), 1MHz (Fast Mode Plus).But, in my lab application, I need to implement 4MHz I2C signal. I had used FPGA logics to achieve 4MHz I2C signal....
Posted on July 25, 2016 at 14:46Hello, I'm trying to find out how UART received data is influenced by noise. STM32F1xx reference manual states that the UART will check three sampled values from the middle of each bit. If one of those three values di...
Posted on July 25, 2016 at 14:15Hello, STM32F0 are my favourite ARM based 32bit MCU. Now I have a design of disel engine control unit for cars and gensets. So we need automotive grade MCU. I am trying hard to find one. But I think not available from...
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...
