Read lessHi , Since this is a three channel gadget, the first channel must be powered by a minimum of 108 volts, so I advise using 12 LEDs for 3 watt . Thanks

I am implementing some low level functions for the library (for the CLRC663 NFC reader chip) I am going to write, based on that Simple SPI communication, but I see something weird.
void CLRC663_write_regs(uint8_t reg, const uint8_t* values, uint8_t len) {
uint8_t tempBuf[len+1], i;
tempBuf[0] = reg;
for (i = 1; i < len+2; i++) tempBuf[i] = values[i-1];
g_transfer_complete = false;
CLRC663_enable();
R_SCI_SPI_Write(&g_spi0_ctrl, &tempBuf, sizeof(tempBuf), SPI_BIT_WIDTH_8_BITS);
while (!g_transfer_complete);
CLRC663_disable();
}
and calling it on the main with this:
CLRC663_write_regs(0x02,&g_master_tx_buff,4);
(consider that g_master_tx_buff is filled with 0xAA, 0xBB, 0xCC, 0xDD)
I have these waveforms:
Consider that the SCI callback is simply:
void sci_spi_callback(spi_callback_args_t *p_args) {
if (SPI_EVENT_TRANSFER_COMPLETE == p_args->event) {
g_master_event_flag = SPI_EVENT_TRANSFER_COMPLETE;
g_transfer_complete = true;
} else {
/* Updating the flag here to capture and handle all other error events */
g_master_event_flag = SPI_EVENT_TRANSFER_ABORTED;
}
}
and the enable/disable function are simple i/O controls
void CLRC663_enable (void) {
R_IOPORT_PinWrite(&g_ioport_ctrl, SPI_SSLA0, BSP_IO_LEVEL_LOW);
}
void CLRC663_disable (void) {
R_IOPORT_PinWrite(&g_ioport_ctrl, SPI_SSLA0, BSP_IO_LEVEL_HIGH);
}
The question is: why I got such delays after CS goes low? And why I got about the same delay when I put the CS high?

I am designing a custom ESP32-C3 board with ESP32-C3-WROOM-02 module, and I see the three strapping pins and the explanation in the datasheet – I think for “normal” operation, I just want SPI boot mode (please feel free to correct me if I’m wrong), but nothing says what happens if I leave GPIO2 floating or if it gets pulled to ground. The technical manual and datasheet are pretty clear that both GPIO8 and GPIO9 cannot both be low during boot, but it’s oddly silent about pin2. Does anyone have any experience with this pin?
Also I plan on programming and debugging using Open OCD and a J-Link, does this make any difference with the strapping pins?

While using ESP32-S3-WROOM-1-N8R8 module for my application. I used GPIO20 as a GPIO input for switch application. I have used external pull up for digital high or low. But in that pin ,there is an inbuilt internal pullup. But it isn’t mentioned in datasheet.
Kindly suggest how to change that pin to Hi-Z state.

Read lessHi, Yes, it will support voltage monitors for up to 12 cells, as well as Li-Ion CoO2, Li-Ion Mn2O4, and Li-Ion FePO4 chemistries. The ISL94212 is available in a 64 Ld TQFP package and has a -40°C to +85°C operational temperature range specification. It does not support 125°. Thanks
