Re: How to change the charging current

Yes you can change the charge current to ~1A by changing the nRF51 FW and defining ENABLE_FAST_CHARGE_1A. Since charging faster will heat up the board more you should probably disable the temp check as well by defining DISABLE_CHARGE_TEMP_CONTROL.

Re: Is one battery enough for BigQuad?

Yes one battery is enough but it is actually possible to use the Crazyflie battery too if there is a use case for this. Secondly,When the BQ-Deck is detected it will automatically switch to brushless motor drivers,so, if I want to control the brushless forward and reverse,should I write codes separa...

Re: Getting started with Bolt and ESC Calibration

I'm not so sure what firmware Air 20A is running. It says on the page it supports up to 500Hz which I guess is servo signal rate. You can use the motorPowerSet parameter to manually control the output servo signal. Check this post to get some ideas.

Re: big quad plus LPS

With some modifications to the BigQuad deck it is possible. Read about it in the wiki here . Getting a good reception could be tricky and ultimately it should be free space around the loco deck antenna. We have tested it with just a 5-10mm of free space from e.g. the bottom if it and still worked bu...

Re: use ledring12.c file

I'm note 100% sure of this either but the timer setting is common for all channels so if you still have the same settings each channel is independent. However I think the motors and ws2812 requires different timer settings.

Re: use ledring12.c file

I think this is a resource collision problem because the TIM4 is used by the motor driver. Could you maybe use TIM3_CH1 on PB4 (IO_3) instead?

Re: Bolt pin N11,N12

You mean that you have connected other signals to these pins from e.g. another MCU? The P0.11 and P0.12 pins are configured as inputs by default so should be no problem if they are driven from something else as long as they are not higher then 5V.

Re: Bolt pin N11,N12

You guessed correctly. The N* pins are connected to the radio MCU, nRF51822, and can be used from that MCU. Check the expansion port pinout for more information.

CF2.1 us using I2C (I2C3), that is why, only Bolt is using SPI.

Re: M2 LED is blue and can't bootloader

Can you get into the bootloader by doing a cold boot? That is by holding down the button while connecting the battery?
