Hello I'm try to connect 1 master and 2 slave, but failed, I use stm32f427VI, and use Truestudio for programing, thanks for your help./* SPI4 init function */ //SLAVE1 static void MX_SPI4_Init(void) { /* SPI4 parameter configuration*/ hspi4.Ins...
[BlueNRG-MS] SPBTLE-RF maximum power output compared to BlueNRG-M0A
Hi,I am using a SPBTLE-RF chip and will switch to the BlueNRG-M0A soon. I am willing to estimated how much I will benefit in term of signal strength using this new chip.SPBTLE-RF chip is advertised (on website) to have a maximum +4dBm TX power output...
Resolved! STUSB4500 PD Controller -- unable to sink 20V/12V
Hi, I am working on a USB PD project. STUSB4500 is used to request the 20V/12V 3A from the source. I flashed the NVM inside of the IC. The writing on the NVM seems to be successful as I can read it back and verifiy it. After reconnecting it, I can re...
How to correctly stop scanning for beacons (entering low current sleep mode again)?
I'm using the BlueNRG-2 with FreeRTOS in Atollic TrueSTUDIO.I succeeded in scanning for beacons using:ret = aci_gap_start_observation_proc(160, 160, 0x00, 0x00, 0x00, 0x00);But after some time I would like to stop scanning and e.g. enter sleep mode a...
How to debug Teseo liv3F RF or liv3F configuration issue, I am using a TESEO liv3F in my design, connected by uart with my stm32L0, the communication works but the system doesn't find any satellites. How can I debug this issue by using the UART com ?
The Teseo's firmware hasn't changed (factory's version). The RF design is the same has the strkt01 design, but my board doesn't find any satellites, GPS and Galileo are activated, I used a GNS1A1 board with the same antenna, I set GPS and Galileo con...
IODD files for STEVAL-IDP003V1 (IO-link device)
Hi all,I have purchased the evaluation kit STEVAL-IDP003V1 (IO-Link device) and want to test it with a master of Siemens (it supports both versions). But I need the IODD files for the master configuration and can't find it anywhere. I already tried ...
Hi All, I'm using STUSB4500 as USB Type C PD controller. When am connecting type C cable from adapter to the board it is able to power up. But when I remove the cable and connect again it is not powering up.
For the next time I have to re-connect the adapter than re-connecting type C cable for powering the board. Please help me to find a solution for this issue.Regards,Vyshnav Krishnan
Toggling the INT pin on an STMPE811 in GPIO mode?
I am not using the touchscreen interface, just using the SMPTE811 device as a GPIO expander. I am talking to it over I2C using the STM32F217IGH6. In fact it's wired together exactly the same as the STM3220g-eval board. I have two STMPE811 chips on my...
L9663-1 PSI5 Transceiver not communicating through SPI
We want to use the L9663 PSI5 Transceiver to interface a sensor. A STM32 Discovery board is being used as the SPI master, in mode 1 (CPOL = 0, CPHA = 1). The SPI clock speed is set to 10MHz. The module configuration is:/* SPI1 parameter configuratio...
