phy6222's Introduction

PHY6222

phyplus: Cortex-M0
L2R2: 96 MHz

简介

PHY6222 内置的高性能多模射频收发机最大发射功率达到10dBm，BLE 1Mbps速率下接收灵敏度-99dBm，BLE 125Kbps速率下接收灵敏度-105dBm，同时提供3dB的解调增益；超低功耗芯片架构使得休眠电流低至0.3uA，峰值收发功耗4.6/4mA，多场景平均应用功耗<10uA，保证常规200mAH的纽扣电池正常供电状态下能够持续工作5年以上。接口资源丰富，拥有超过20个GPIO接口。

拥有基于Bluetooth LE 5.2的自主知识产权全栈蓝牙方案，支持包括SIG-Mesh全角色组网、AoA/AoD无线定位、2Mbps高速率模式、BLE长距离模式、主从配对一主多从、扩展广播/周期广播在内的主流BLE功能。支持自主知识产权的多协议栈：Matter (Bluetooth LE+Zigbee) 多协议共存；PhyPlus私有2.4GHz协议栈。

关键参数

96 MHz Cortex-M0 (<60uA/MHz)
64KB SRAM + 96KB ROM + 256bit efuse
可选128KB-8M FLASH
多协议支持 Matter BLE+ZigBee
工作电压：1.8V-3.6V

资源收录

选型建议

PHY6222 是涂鸦蓝牙模组 BP系列的主控芯片

相对于QFN32封装的PHY6222，工业场景也可选SSOP24封装的PHY6252

phy6222's Issues

I2C not working

I am trying to develop device with i2c modules. Unfortunatelly my PHY6222 does not comunicate with any module. There is no activity on SCL and SDA lines.
My code:

hal_i2c_pin_init(I2C_1, P1, P0);
void* i2c_inst_main = hal_i2c_init(I2C_1,I2C_CLOCK_100K);

uint8_t address;
int err_code = 0;
uint8_t sample_data = 0;
bool detected_device = false;

LOG_DEBUG("TWI scanner started.");
for (address = 1; address <= 127; address++) { 
    err_code = hal_i2c_read(i2c_inst_main, address, 0x01, &sample_data, sizeof(sample_data)); 

    if (sample_data != PPlus_SUCCESS) { 
        detected_device = true;
        LOG_DEBUG("\r\nDevice detected at address 0x%x.\r\n", address);
    }
    else{
        LOG_DEBUG("Error: %d at 0x%x.\r\n", err_code, address);
    }
}

if (!detected_device) {
    LOG_DEBUG("\r\nNo device was found.\r\n");
}

LOG_DEBUG("TWI device scan ended.");

My code is in function called from osalInitTasks(void).

In result I get error 13 (PPlus_ERR_TIMEOUT) for all I2C address.

I use bleUart_at example. I add i2c.h import, and i add i2c.c file to project.
There is no difference between: I2C_1 and I2C_0, clock: I2C_CLOCK_100K and I2C_CLOCK_400K does not change anything.
These pins aren't use by me to any other tasks.
I try also pins P18 and P20 and thats the same. Pins are only pull up by PHY6222.
I use PHY6222 board V1.7 and self solded board, there are no differences.
Resistors don't make any difference.

What am I doing wrong?
Could you add I2C example to sdk?
