Interface and connectivity ICs

the qspi flash memory device S25FL512S here https://github.com/STMicroelectronics/stm32-s25fl512s Is there any low level driver code for risc-v or other cpu ?

Can you turn off the radio (BLE) on a BlueNRG LP (355MC)?

I am designing some firmware for a BlueNRG LP (355MC) based device with several sensors. At certain points in the device's processing/lifecycle, I need to turn off the BLE and/or radio to conserve power. In fact, I only need the device to have BLE co...

No access to STS1TX following power-up

Now and again, following power-up, we find the STS1TX in our product in a state where we cannot interface with it. The SPI and GPIO lines are outputting ~2V levels, so no commands can be sent.Typically, cycling power may allow the chip to initialise ...

STS1TX user here The SMPS sub system seems to crash on power-up at random times, on some (but not all) chips What could be causing this ?

Very standard "app note" circuitGood decoupling. 2.8v switched supply railXO is up within 350uS of startupDevice is programmed about 100uS after detection of the "reset OK" state

BLE Mesh without storing network data to NVM

I am trying to acheive a BLE Mesh system where no network data will be stored to NVM, i.e. system will need to reconfigure on every reset.The network consist of one PRV and a handfull of LPNs, the LPNs will be mobile and will therefore enter and leav...

S2LP maximum power transmit problem

hi,I am trying to transmit at maximum power using S2-LP. I set the configuration registers using S2-LP DK Application tool version 1.3.4. I set output power as 14dBm, check the MAX power box, choose HPM mode (in PM mode section), set 1600mV SMPS volt...

I'm using ST33HTPH2X32AHD8 in my design and would like ST Micro to review the design. I prefer email or personal messages instead of sharing in the forum.
