I'm using a STM32G4 and communicating with multiple devices that use a 16 bit + 1 bit (write/read bit followed by six register address bits, 16 data bits, and a parity bit MSB first) on SPI. What I'm seeing is on transfers i have to shift my data 1 b...
I'd like to add an LED indicator to the FLT pin so it sinks current when it becomes active low. The LED anaode would be tide high with a resistor in series. The spec sheet says this pin has a resistance of 250Ohms when active. How much current can t...
My application will manage multiple power sources (battery, DC, UCPD) and have a TCPP01-M12 protecting CCx lines. With this configuration the STM32G4 could already be powered by DC or battery, but must be able to negotiate 20V on VBUS. I want to avoi...
Can anyone explain a usage case or purpose for the 4 Internal and 3 External DACs?Can you operate all three external DACs simultaneously to provide 3 reference voltages?
I want to create a power distribution system that can accept up to three supplied (AC/DC, USB, and Battery. At the end of VBUS will be the management system that will choose the highest voltage and use that as primary supply.Would like some suggestio...
