Ask questions and find answers on connectivity ICs, focusing on protocols and I2C challenges on STM32 Nucleo boards and BlueNRG products.
I have seen some thread about this topic but it's still not clear to me.I'm using the x-nucleo-BNRG2A1 which embed a BNRG-M2SP. Is it possible to increase the ATT_MTU size ? for example in the sample example code we do a aci_gatt_exchange_config(conn...
Hello,Good day!We have a RS485 communication system and we are usign the ST485B, but we recently had an issue with a couple of PCBs(attached picture)We are using an external DC/DC converter as 5V power supply (attached schematic). I followed applicat...
Hi,Is there any information regarding whether there are internal clamping diodes to VDD and GND on the open-drain outputs (RP_1A5, RP_3A, ATTACH, ALERT, A_B_SIDE, GPIO) of the STUSB4500L device? If these outputs have external pull-up resistors that c...
Hello, I've designed a board based on the EVB schematics and layout. I need to output a frequency of 1250 MHz.I managed to make it work with the on-board 100 MHz oscillator, and it works well with 25 MHz external clock, but I can't find a way to use ...
Im developing a custom board with a non ST microcontroller, the board has 6 mosfets and i wish to monitor them using ST's TSC1641 Is it possible to have 6 of the aforementioned sensors to monitor each mosfet? Also is the exposed pad at the center rea...
As noted here, AN4494 contains a figure which captures the prescribed test procedure as it appears on the SPI bus.The annotations in the figure (specifically, step 6) do not correspond to the test procedure, which also includes a 6-byte read in step ...
Hello!I am asking for help or advice from experienced colleagues. I am developing a device in which the STM32G030C8T6 microcontroller “catches-up” the upstream signal from the 74HC04 inverter with the TIM1 (CH2, as trigger source) timer and should gi...
How can we increase the output power to 16dBm of S2-LP - in combination with the SigFox stack? In the SigFox_PushButton_Project we tried to set register PA_POWER8 to 0x01 to turn the output power up.StatusByte = SdkEvalSpiWriteRegisters(0x5A, 0x01, p...
What is the simplest way to set the power amplifier?Unfortunately the APIs require involvement with the PA ramps and index configurations.void S2LPRadioSetPALeveldBm(uint8_t cIndex, int32_t lPowerdBm) void S2LPRadioSetMaxPALevel(SFunctionalState xNew...
Dear Community,I am using the STEVAL-IHP005V1 development platform and have some queries regarding the SPI communication protocol between the Application MCU and the Modem MCU (ST7540). I would appreciate your assistance in addressing the following q...
