Posted on November 09, 2016 at 21:30How much I can put on Vref without lossing bit? I can read 8 bit without nise (12 bit is noisy) when the Vref is 3.3V. however, my sensor show maximum 12 (decimal). I wan to get more resolution. Therefore I want t...
Posted on November 09, 2016 at 18:50HelloI have some questions about stm32f303cb usb module:1- If the EP0 receive buffer is set to 1 bytes, how will received data be handled during setup packet reception (bmRequestType, bRequest,... totaling 8 bytes...
Posted on November 08, 2016 at 19:59Hi, I want to generate short pulses on channels 1, 2 and 3 of TIM4. Pulses on each channel must be shifted relative to other channels, just like on image below:Main idea is:At first I set TIM4 mode to TIM_OCMode_A...
Posted on November 08, 2016 at 10:28Hi All,How can I calculate power consumption of STM32 MCU (only ADC peripheral is turned on) for a period ? From the Data Sheet it is given that for 100Mhz Clock it consumes 12.6mA, How much it consumes for 1 seco...
Posted on November 09, 2016 at 04:51I now develop Modbus transportation compatible with Modicon RTU and I was going to use the opportunity of detecting IDLE state by the UART. But the duration value of IDLE character is fixed and equal one frame. It...
