Posted on June 08, 2018 at 14:40 Hello everyone, I have 9 pins of ADC that each of them will received signal from function generator 20 kHz. I want to use ADC to store the data inside an array by using DMA2. ADC1 has 3 pins, ADC2 has 3 pins, ADC3...
Posted on June 11, 2018 at 17:32I am developing an battery operatoad device, but at most of other IC are opearting form 1.8V that I would like to run STM32 from 1.8V as well. But batttery will be 3V, as other things need 3V as well. So qusetion is -...
Posted on June 11, 2018 at 15:23Hello all,I am using STM32L432KB controller with LIS2DE12 accelerometer over I2C3.On the controller side,- when I use Normal mode (100KHz) with blocking API HAL_I2C_Mem_Read(), it took about 500 uSec to read a single ...
