Hi,
We tried to use Epson TSX-3225 series crystal, but it didn't work. Load capacitance is 9pF - is that the only reason why it didn't work?
We need to select a good and cheap crystal which works -40C to +85C. Can you help with that? We changed the crystal to Abracon and seems that it started to oscillate.

Hi Dialog.
我成功的广告ded a timer0 interrupt on DSPS device project. Every time the timer creates an interrupt, i read data from spi and then data are added into uart to ble buffer in order to send them via bluetooth. The timer interrupt handler is described below.
void SWTIM_Handler(void)
{
NVIC_DisableIRQ(SWTIM_IRQn);
readMcp3004();
my_timer_init(50000);
NVIC_EnableIRQ(SWTIM_IRQn);
}
void readMcp3004(void)
{

Hi Dialog,
In AN-B-029 for Developing a DA14580 Bluetooth profile using sample128, creation of new read/notify characteristic is given. However I want to implement write/read characteristic in my project. What should I do? Please help.
Hi Dialog Team ,
I've gone through the code for the serial port service, and since it is set up with pointers that are shared between UART and SPS, I'm not sure the best way to send data from the app to a mobile device. For example, I'd like to send ASCII values from sensors periodically, but what is the best way to do this using the example code, should I be allocating my own pointers in memory and then calling app_uart_push()? Maybe a couple lines example code would help. Thanks!
void ext_wakeup_enable(uint32_t port, uint32_t pin, uint8_t polarity)
{
rwip_env.ext_wakeup_enable = 2;
#if DEVELOPMENT_DEBUG
RESERVE_GPIO( EXT_WAKEUP_GPIO, (GPIO_PORT) port, (GPIO_PIN) pin, PID_GPIO );
#endif
if ( polarity == 0 ) // active low
GPIO_ConfigurePin((GPIO_PORT) port, (GPIO_PIN) pin, INPUT_PULLUP, PID_GPIO, false ); // active low. Set default to input high.
else // active high
GPIO_ConfigurePin( (GPIO_PORT) port, (GPIO_PIN) pin, INPUT_PULLDOWN, PID_GPIO, false ); // active high. Set default to input low.
Dear Sir/Madam,
I tried to run prox_reporter on the basic kit compatible board.
I used Keil's debug menu to run the code. To my surprise, the monitor can't find it. Looks like the advertisement is stopped.
I burned the code into the flash of the board. After the reset, the monitor can scan and connect to the prox_reporter without any issue.
Why does the JLink debug has the different behaviour compare to execution from flash?
Thanks!
Regards,
Simon
Hi Dialog,
I want to use the DA14580 in a PCB single layer. My substrat is FR4 probably.
And i don't know what is the best antenna who don't take a lot of space.
I think to use a printed IFA, it's a good choice? Where can i found a footprint of a IFA?
Thanks
Hi,
I built a secondary bootloader with my image using mkimage. This gives me a binary output and works well
However I notice that when I program the image into my i2C EEPROM, anything above 0x10000 is not programmed (for example, the product header).
Hi：
how can i transfer the hex file to the image array?
Thks
