Hi there,
I use DA14531 TINY module with Codeless SDK 6.380.10.4 and factory compiled codeless_531_standalone_set_two.hex image along with TI's HDC1000 sensor. Problems occur when I read or write to sensor registers.
By reading a register, the commands are as follows (see attached console session):
AT+IOCFG=9,7
AT+IOCFG=8,8
AT+I2CCFG=7,100,16
AT+I2CREAD=0x40,0xFE
Hello. We are planning to use either the SLG46824 or SLG46826 device in some new products and really welcome the multi-time programming over I2C of these components - simply due to lower risk vs. use of OTP.
We have built up the IP over this last weekend and the simulation is showing promise to be correct. Will test against the true hardware this week on your kits.
A few questions on this component and sourcing:
Hi, I'm trying to read the temperature from Si705. I have connectiong to the sensor, as I have tested it, when I read the firmware-version using the measurement-process described in this pdf (https://www.silabs.com/documents/public/data-sheets/Si7050-1-3-4-5-A20.pdf) page 16. However, when I try to read the temperature, my output ends up being 0, 0. As of now my code is this:
uint8_t cmd;
uint8_t data[2];
uint16_t degrees;
cmd = Temp_H;
Hi,
I have two devices on my I2C bus (eeprom and another device) and I have external pull ups attached on the bus - scl, sda (4.7k). Post addition of the external pull-ups I observe a bump in current consumption - about 500uA continuous consumption(also when chip sleeps). This goes away once the external pull-ups are removed. A potential reason might be that the i2c lines are not being deactivated.
My code for initializing i2c is like this:
we now use two I2C devices in our DA14583 project, the devices have different slave address, so i don`t know how to use the I2C dirver from the SDK to configure my devices,like how to use the function 'i2c_eeprom_init()' to initilize the I2C interface. And i also want to know the two devices can use the same IOs(SDA,SCL in the two devices tied with just two IOs) or they can use different IOs(SDA,SCL in the two devices tied with four IOs).
With IO6 connected to SDA, it seems to fail to program, giving the "Chip is absent or misplaced" error.
During the programming attempt, SDA reaches 3.3V about 1mS after starting, but goes to 0 at about 3.3mS.
Is a factory-set value for IO6 being asserted then, and if so, can it be changed?
你好，请问下关于充电电池的几个问题：
1、pxp例子里关于充电电池配置文件custom_socf_battery_profile.h文件内的vol_chg_0_0 = 3067; //120mA charging，这个值是怎么算出来的，有公式吗，看了UM-B-075_DA1468x_State_of_Charge_Functionality_v1.2_0.pdf文档，需要一个硬件设备连接后才能使用，目前没有这个设备；
2、dg_configBATTERY_CHARGE_VOLTAGE和dg_configBATTERY_TYPE_CUSTOM_ADC_VOLTAGE 这两个有什么区别？
3、vol_dis_low_0和vol_dis_high_0 必须通过UM-B-075这个文档中应用程序测出吗，有其它方式吗？
Hi all,
I am writing to DA14580 I need to initialize and work with I2C in a slave mode, Can you please guide me how to do it?
I am getting the data in I2C and send it over the BLE
Regards,
I am using the i2c adapters (in master mode) for doing asynchronous writes or reads that waits FOREVER for an OS_EVENT to be signalled from the callback.
However instead of waiting FOREVER I want to be able to set a timeout value so that it doesn't get stuck if say there's no device on the bus.
Is it possible to convert UART to I2C with GPAK?
