Posted on May 17, 2011 at 13:08I am trying to read a block of data from a flash memory device into the STM32 using SPI and DMA. What I noticed on the o-scope is that when I write the command, 24-address, and dummy-byte there is a clock from the MCU ...
Posted on May 17, 2011 at 13:07Hi Andreas, Thanks for the response. I read in the reference manual (pg 373) the following comments on the ADON bit: ------------------------------------------------------------------- This bit is set and cleared by s...
Posted on May 17, 2011 at 13:07Thanks for the ideas. My guess is that the state of the analog input can be anything when the ADC is initialized so it should not matter if the 24v beats Vdda. The voltage divider is just a simple resistor divider on t...
Posted on May 17, 2011 at 13:07Hi Everyone, I am using the STM32F103 in the 64-pin package. I have 3 external inputs to the ADC: 1) 24v through a voltage divider --> normal should read around 2.18v 2) 3v through a voltage divider --> normal should ...
