Hello,
I am attempting to implement the technical note for a quadrature encoder to SPI-based counter described inAN-CM-277in order to take a load off our microprocessor as it's needing to keep track of 18 encoders.
I've purchased the following items from Digikey:
Dear Dialog Team,
这个项目我正在使用电动水valve that require BLE5.0
Please advise if DA14585 can drive/control HFET1 (if not please advise other Dialog althernative solution)
Moreover, i'm having trable to find the best HFET1 P\N to fit my application (attached valve datasheet)
if you have a refrance design/scehmtic it would be perfect
Thanks
Roie
你好，
在Secondary Bootloader 工程中，将image加载到SRAM时为何SUPPORT_AN_B_001不使能，如果使能就是从OTP中加载吗？
从spi flash中加载和使能SUPPORT_AN_B_001有何不同？
如果我想把image header 和 product header 的地址改变不使用0x7052 0x7051的话是否能实现？
/************** AN-B-001 based image /fast bootloader section **************/
// Define it if
// if AN-B-001 based image is burned in SPI flash and the bootloader is running from the OTP
#undef SUPPORT_AN_B_001 //Enable it for the secondary bootloader
//从spi flash 中加载函数如下：
Hi,
According to the datasheet of DA7212 Page 62, there is no need of MCLK when DA7212 is interfaced with the processor in slave mode. I have interfaced ard-audio-da7212 board with my Arduino MKRZERO. Arduino MKRZERO is capable of generating the required I2S signals like BCLK,WCLK and DATOUT. My question is do I have to provide MCLK to ard-audio-da7212 from MKRZERO?
regards,
Niradat.
我的应用是DA14580平时工作在扩展睡眠模式，在满足一定条件后进入深度睡眠且不需要被唤醒，进入深度睡眠后再次工作只有被复位脚复位。在memory宏定义中使用扩展睡眠，undef debug, undef development,使用otp,使用片内rcx20。 现在问题是在有些情况下(比如广播超时关闭后)进入深度睡眠后几秒钟内会被唤醒(100%)。
用keil仿真在进入深度睡眠前确认了以下几点：
1、APP用到的定时器已被全部关闭。
2、系统10S定时器已被关闭(sleep_ext_force =true)
3、蓝牙已被关闭(若在连接状态，连接断开后不再广播；若在广播状态，关闭广播)
您好：
目前在开发DA14580/DA14585做主机，可以一对多的功能（在DA14585_DSPS_v_6.150.2的主机例程里修改）。但是对于主机一对多功能并没有太多理解，不知道从何下手。大概有以下几个方面不是很理解。
1：DA14580/DA1585做主机，并且可以一对多，需要修改哪些参数、变量以及函数。影响连接个数的因素是哪些？
2：我想知道调用gapm_adv_report_ind_handler函数后，到执行gapc_connection_req_ind_handler函数这中间还有哪些步骤？
我仿真的时候发现，成功连接一个蓝牙后，如果继续user_scan_start();还是能对第二个蓝牙广播report的，但是gapc_connection_req_ind_handler就进不去了。
3：主机连接从机后，需要创建profile。那连接多个从机，需要创建多个profile（假如profile类型是一样的），还是只需创建一个profile？会不会影响连接个数？
我按照Dialog SDK 5.0.3培训材料，基于ble_app_profile工程，修改了user_catch_rest_hndl函数中的case CUST1_IDX_LED_STATE_VAL，作为接收我的手机端传来的命令，进一步在主循环里进行判断操作。
代码如下：
void user_catch_rest_hndl(ke_msg_id_t const msgid,
void const *param,
ke_task_id_t const dest_id,
ke_task_id_t const src_id)
{
switch(msgid)
{
case CUSTS1_VAL_WRITE_IND: //特征值已被写入
{
struct custs1_val_write_ind const *msg_param = (struct custs1_val_write_ind const *)(param);
I run the ble_central demo on the DA14683 evaluation board but cannot connect the remote device. The peripheral device address is set correctly and the iphone or PC can connect it.
The ble_peripheral demo can work on this evaluation board.
Seems it is in the connecting loop but cannot get any notify information. what's the reason the evaluation board cannot connect to the peripheral?
Looking for a PMIC to support LPDDR5 devices.
Do you have something like the DA9062 or is tis best choice.
Thanks,
Richard
Hello! I tried programming da14580 with the codeless_580_v5.380.5.4.0.hex file. I set the jumpers on the board, like here:
http://lpccs-docs.dialog-semiconductor.com/da1458x_codeless/howToUse.htm...(Basic).
When I click Download, I see the following data in the logger:
