Misbehaving gpio pins
Posted byjagath5250 points 3 repliesHello
I am using Da1469x MCU and social distancing project with Wira SDK 10.440.8.6 for our custom board.
Board has LCD with SPI communication and Pixart with I2C communication.
1. In custom board ST7735 LCD spi pins and their control pins are connected to P0_0 to P0_3. The problem is SPI communication is not happening in P0_1(MOSI) and P0_2 (SCLK).
2. If we connect only MOSI and SCLK pins to other gpio pins LCD is working fine only in battery, but if device connects to charge then lcd is misbehaving and not working properly.
3. Pixart needs one GPIO interrupt to run its algorithm.
If pixart interrupt is connected to GPIO P0_5 and P1_5 then fine pixart working properly, but
如果其他GPIO连接到诸如P0_17，则我正在连续中断，其中算法无法正常运行。
谢谢

Hello PM_dialog
我正在使用p017 gpio，
How to change the gpio strength and how to modify PAD_WEAK_CTRL_REG (0x50020B00)
谢谢

Hi Jagath,
1. Please check note 5 (page 62) from theDA1469x Datasheet。P0_00 ... P0_05引脚只能用作1.8V的GPIO，因为它是QSPI类型的垫。这是记录在的AN-B-066：硬件设计指南too. These pins can be used at 1.8 V (V18P) only, cannot be used at 3 V. These six GPIOs have pull-up and pull-down resistors with a value of 40 KΩ. So, are you using these pins at 1.8V or 3V ?
2. Can you please indicate which GPIOs?
3. Please check the AN-N-066. According to the document, there is the reduced driving strength (RDS) functionality on 13 pins (Table 9). The GPIOs and strength can be accessed/modified from register PAD_WEAK_CTRL_REG (0x50020B00). These pins are available for both packages. This mode should be coupled with the selection of the V18P supply rail for these pins. When selecting the V30 rail as supply, the RDS functionality is not supported. P0_17 indicates the start/end of the XTAL settling process.
Thanks, PM_Dialog
