This year I took part in Hackctober Fest. I have to make 4 valid pull requests in order to win a Tshirt. I need to do it by 31oct and come within 75000 people in order to win.
Can I help you in any way, So in return you could accept my pull requests?

I saw your videos on youtube. I have seen that you work in Keil Ide, I use STM32Cube.
Can I add my files to your Repo? so that people working on Stm32Cube could also benefit.

Or any other help, please do tell. I use STM32F407VG Board.

Thank you, Sir
Sorry If I bothered you.

Actual Behavior

Bit TX_DS (5) in status register is no set. Library tested on STM32F103C8T6. The problem is in NRF24_startWrite() function when BIT_PWR_UP is set and BIT_PRIM_RX is clear.

Step to reproduce

Before set BIT_PWR_UP and clear BIT_PRIM_RX in NRF24_startWrite() function set CE line as LOW. After set and clear bits change state on CE line.

The lcd16x2_i2c.h file contains the code from the lcd16x2_i2c.c file.

Hi, i just went through the code, in the function:
void CS43_Init(I2C_HandleTypeDef i2c_handle, CS43_MODE outputMode)
I found this:

iData[1] &= (1 << 5); // Clear all bits except bit 5 which is reserved
iData[1] &= ~(1 << 7);  // Slave
iData[1] &= ~(1 << 6);  // Clock polarity: Not inverted
iData[1] &= ~(1 << 4);  // No DSP mode
iData[1] &= ~(1 << 2);  // Left justified, up to 24 bit (default)
iData[1] |= (1 << 2);

I guess this;
iData[1] &= ~(1 << 2); // Left justified, up to 24 bit (default)
should be
iData[1] &= ~(1 << 3); // Left justified, up to 24 bit (default)
right ?

I guess this is not an issue here, since the bit is 0 by default anyway, but just to know,

Great code by the way, thanks for sharing !

HI MYaqoob,
I am using your library for NRF24L01+, STM32-Tutorials\Tutorial 24 - NRF24L01 Radio Transceiver

I have the following issue, Would you please help me understanding what is wrong.PFA

1. Previously it was receiving correct strings, but now I am just receiving as "TTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTT"
   My transmission strings look like this

• ---------- Configured as Transmitter ------------
  Tx Count= 6566, Tx Failed= 0, Rx Count= 0, Rx Failed= 0

'T' is first letter which is transmitted, but it doesn't receives strings after that, I checked with SPI analyser.

2. Sometime it goes to Power down mode abruptly and all value of status/config register becomes zero.
   I added NRF24_powerUp(); while changing mode Tx to Rx, but nothing helps.

I tried this library for stm32f103c8t6 but it didn't work. I added your update later, but it didn't happen again. In the update I mean: NRF24_startWrite function added this line NRF24_ce(0); I would appreciate if you help. good work

hello mohammed..

i suggest using somthing like

#define custom_delay(x) HAL_delay(x)

and use it all over the library so you can later port it easily on something like FreeRTOS
refering to lcd i2c directory ^

that's great tutorial.
I have seen and implemented Printf in UART, you should also include that in your tutorial.
Also, I want to know how to use Scanf in UART.
If you have any idea or any reference, please share.

Can u do a video on I2C interface multiple TMPx75 Sensors with freertos concept ?
Where each task is about single TMPx75 slave

I am trying to implement 20x4 LCD with your Library its working fine but i am getting characters only upto 16. I want to use complete 20x4 lcd how that can be done ?
