UART/USART - enable HDSEL and SWAP at the same time?

2020-01-04
Hi All,Could anyone tell me what happens on an STM32H750 (or other STM32) UART if you enable both the HDSEL bit (half-duplex mode using only the TX pin) and the SWAP bit (switch TX and RX pins) at the same time? Will this get me a half-duplex UART us...

What does the DEN_A/G pin on the LSM9DS1 actually do?

2015-02-10
Posted on February 10, 2015 at 15:24The title really says it all. The pin description for the LSM9DS1 says that the DEN_A/G pin is the Accelerometer/Gyroscope Data Enable. This sounds important, but I can't see anywhere in the datasheet that explai...

STM32F401 reference manual

2014-06-25
Posted on June 25, 2014 at 15:07I'm sure that this is a really silly question, but is there actually a reference manual for the STM32F401 chips? I can't see one on the design resources page. The STM32F401 Discovery documentation refers to ''RM0344''...

SPI to the LSM9DS0 using only four pins

2014-02-23
Posted on February 23, 2014 at 09:41Quick question: I've got a 4-pin SPI port on an STM32F3 available (and no other pins; they're all occupied) and I need to talk to an LSM9DS0 sensor. The LSM9DS0 has two separate SPI interfaces, one for the gyro pa...
