Hello guys. I am trying to drive an audio DAC(PCM1774RGPR) using I2S protocol with STM32H750, and I found that the I2S Master Clock output is disabled due to conflict with LTDC pins. I also found that the DAC requires a SCKI input, which I think that...
Posted on February 13, 2017 at 20:17Hello everyone.I've been working for a long time with SPBTLE-RF modules in our project. I never experienced any problems with these modules.But now we've redesigned our PCB and are going to use BlueNRG-MS chips di...
Dear ST Community,Aside from the SPIRIT1 DK, are there any short and simple examples for basic packet transmisstion and reception with SPIRIT1? The W-MBUS is desirable, but not mandatory for my use case. I have gone through the frequency and channel ...
MODE_TYPE in MOD0 register of SPIRIT1 only support 2-FSK, GFSK, ASK/OOK, and MSK settings. How can I set SPIRIT1 to GMSK mode?
Hi,I'm trying to setup a virtual timer, which fires every 400us, for triggering a ADC conversion.I found that when this timer is running, even if i comment all the code inside the callback, it would block the BLE radio activity, for example advertisi...
hello everyone, i am using stm32f407 discovery board and i would receive data from a device (load cell amplifier) which communicates via RS232. So my question is : can i use a simple USART in my stm32f4 to receive data ? or i need to use ( RS232 -->...
Hi Can anyone please guide me on how to operate st7580 at specific frequency. i am trying to operate it on 83Khz and BFSK
