[What to do] The first plate is smooth [Copy link]

 

 

Leisure water stickers, play the board

Looked at the user manual

There is a GOIOMUX

Wiring will be much easier

In addition to ADC and wakeup

Other IO can basically be used by any peripherals

Internal structure

The ARM core can access all RAM, followed by the peripheral DMA

DSP core is second, BB can only use 16kB

By the way, what is BB?

The manual only introduces one DBB (Digital baseband)

Link layer functions for the Bluetooth protocol stack

I can't help but hear a sweet child's voice: It is it, it is it, Bluetooth's best friend, little BB~~~

RAM uses two types: common DRAM and the rumored powerful PRAM.

It is said that PRAM has lower power consumption and faster speed, making it the best partner for Bluetooth SOC

There is a detail in the picture, the DSP core also has a JTAG logo

Will it lead to some IO?

Is there any original XD to show up for PY?

There's no water. Let's light a lamp.

Configure the environment according to the manual

Open it and take a look

Familiar recipe, familiar taste

Unable to contain the admiration in my heart, I shouted: Eclipse is great!

Change IO, turn on the light

Lighting completed

Let’s take a look at GPIO-MUX

Follow ADC_UART down

The RSL10-SENSE-GEVB I have only one free IO port DIO3

Just post a picture to see the process

Change DIO[x] to solve the problem

Which pin port is blocked?

No need for xxxxxCubeMX anymore

Emma, it's really...

Use Bluetooth to focus on the broadcast

Follow a ble_central_peripheral project

Broadcast configuration is mainly concentrated in app_config.c and app.h

Broadcast parameters such as device name and duration interval are mainly configured in app.h

The broadcast composition is handled by APP_SetAdvScanData in app_config.c

Random code

Use SOC built-in MAC address

The broadcast name was changed to LJJ3166

Manufacturer changed to Xiaomi

Add LucyDog field to broadcast packets

Scan response packet changed to Hi , EEWorld, I'm Ljj3166!!

Modify the result

The whole process of pulling the board is still relatively smooth

Unfortunately, I didn't see the official SDK package.

Just be able to download routines online

Finish the work

Awesome, learned something.

I have never seen such an easy to understand post.

eclipse is fun

The article really reflects the feeling of playing board, looking forward to the follow-up haha

Please give me the Silky, I didn’t apply for it…

What are the ARM cores and DSP cores? How do the ARM cores and DSP cores communicate with each other?

The stack catches exceptions gracefully again

Anyone who plays it knows, yeah

The attitude of playing the board is everything

The supervisor said that you can apply for a chip

Get the chip

Just a friendly price - 5 times the market price for you

Almost half price

If you self-destruct black silk uncensored binding add id

Free to you

bqgup posted on 2021-4-30 07:53 Does it include arm core and dsp core? How do arm core and dsp core communicate with each other

Not sure

But it seems there is a routine, I haven't studied it

Damn, it’s so cheap, great price, give me the quantity of 1K.
