Hi,Some time ago I wrote a software with some changes from this library and successfully tested it with the STEVAL-FKI868V1 board and a ST board (STM32F779 EVAL).Now I made my own hardware with a little changes in the microcontroller pins. Communicat...
Hi I am developing RF transceiver with S2-LPQTR, frequency range 413-479 MHz. Also I bought BALF-SPI2-02D3 which applies to 433MHz impedance matched balun filter. Based on the mentioned details, I referred to the following schematics for designing t...
I want to use this configuration according to the L9663 Datasheet "Trigger via SPI with an upstream data buffer. The microcontroller sends the corresponding SPI command to send a sync pulse. Then, the sync pulse triggers the generator based on the va...
Hello, maybe you have an idea!?!The STEVAL-IHP005V1 is connected to a 12V power supply and a series regulator that makes 3.3V from the same 12V. The LED flashes briefly when switched on and then lights up constantlyorange.The STEVAL-IHP005V1 is conne...
Hello everyone,I’m seeking guidance on using the STEVAL-USBI2CFT as a voltage shifter (to 3.3V) and a communication bridge between my laptop and an MSP430 IC. According to UM3226, the STEVAL-USBI2CFT uses the FT260Q chip and should not require extra ...
Hallo,So I have this ADV_IND advertisement mode, which works just fine: // Advertising definitions ret = aci_gap_set_discoverable(ADV_IND, // Connectable undirected advertising (ADV_I...
Hi, I am starting to learn and use Bluenrg-2 BCN002-V1 and tried to flash it using the example provided in stsw-bluetile-dk and Nucleo-F411RE. When trying to flash examples, I performed a mass erase and I cannot recover the board anymore i.e. the BC...
HiWe are currently working on a design involving the TSV912IQ2T operational amplifier for piezo film sensor signal detection. In our previous tests using the LM358 op-amp, the design worked perfectly. However, upon switching to the TSV912IQ2T, we are...
Hi,I am trying to write the IQ data to the SD card (i.e., write the received CTE pkt to the SD card). However, I found that Bluenrg-332ac has a cortex M0 core, which may not be able to drive an SD card. Is it possible to use this cortex M0 core for S...
Hi I'm using this device in a space design. I just want to clarify the voltage requirements. In all cases, I have Vdd1 >= Vdd2, as specified. However, I'm using the device in these configurations and I want to confirm that the voltage levels are v...
