I have narrowed the issue to the function I am using to read 2 bytes from the slave. Other library like PIC Microchip and STM32 does not require. The address my be translate to 7bit so shift the value one bit to the right. It is necessary add a pull-up on both I2C pins. SCL and SDA are on the same bus of SCL1 and SDA1 so it is useless to use the second one.

After some test I can share my experience on Wire library. WIRED is providing unlimited free access to stories about the coronavirus pandemic. Updated 3-25-2020 11:35 am EDT: This story was updated with information about the Internet Archive's new National Emergency Library. “As long as you keep a library central to your life, you will always see how relevant it can be.” “At some point a library is going to save your ass,” Brixey says.

A “ don’t know what you’ve got until it’s gone” type situation, perhaps, that could generate more public support for libraries moving forward.

The hope among library advocates is that the coronavirus closures will spark more awareness of the services the brick-and-mortar institutions offer. It’s going to be tough for us to do that, because we’re going to be faced with either flat budgets or declining budgets, because our funders won’t have the money to fund us the way they do in the good economic times.” The I2C protocol involves using two lines to send and receive data: a serial clock pin (SCL) that the Arduino Master board pulses at a regular interval, and a serial data pin. “We’re probably going to lose staff and lose programming all at a time when people need us the most,” Pearson says. This example shows how to read a Devantech SRFxx, an ultra-sonic range finder which communicates via the I2C synchronous serial protocol, using Arduino's Wire Library. Combine a surplus of increasingly desperate people with an underfunded library staff and things can get ugly. According to a 2010 report by the ALA, libraries in 24 states had their funding slashed during the recession of the late 2000s. During economic downturns, library patronage surges, as millions more people are drawn by free and low-cost resources, job-seeking programs chief among them.

While libraries have struggled during their time in suspended animation, more hardships may come after the coronavirus pandemic runs its course.
